Abstract (en)
A method for determining motion vectors for a current block (E) in a picture to be coded is disclosed, comprising: obtaining first and second motion vectors of blocks (A, B, C) other than the current block (E); obtaining a reference picture index of the other blocks (A, B, C); and determining first and second prediction motion vectors of the current block (E) by using the first and second motion vectors of the other blocks (A, B, C); wherein the step of determining first and second prediction motion vectors of the current block (E) is performed by using the reference picture index; wherein the step of determining first and second prediction motion vectors of the current block (E) includes applying a median operation to the first motion vectors of the other blocks (A, B, C) and to the second motion vectors of the other blocks (A, B, C); wherein the other blocks (A, B, C) are neighboring the current block (E) at a left, top and top right position, respectively; and wherein the first and second motion vectors of the current block (E) are derived by adding first and second motion vector differences to the first and second prediction motion vectors of the current block (E).
